解决Caused by: java.lang.IllegalArgumentException: Result Maps collection does not contain value for com.geek.dao.ContentDao.Integer
mybatis报错:Caused by: java.lang.IllegalArgumentException: Result Maps collection does not contain value for com.geek.dao.ContentDao.Integer
出错原因:一个手误
<select id="selectAllFirstNavigationName" resultMap="firstNavigation">
SELECT first_navigation_name
FROM first_navigation
</select>
修改方法:将resultMap修改为resultType,因为返回的是基本的数据类型
resultType和resultMap的区别:resultType是直接表示返回类型的,而resultMap则是对外部ResultMap的引用
